Description

Technical Field

[0001] This utility model relates to the field of hygiene products, and in particular to a fast-conducting and leak-proof diaper with conical permeable holes. Background Technology

[0002] In the field of infant care, diapers are an essential daily necessity, and their performance directly affects the health and comfort of infants. Traditional diapers often suffer from slow absorption, uneven absorption, and easy side leakage when absorbing urine. These problems not only affect the infant's wearing experience but may also increase the risk of skin problems such as diaper rash. Therefore, how to improve the absorption speed, absorbency, and leak-proof performance of diapers has become a focus of industry attention.

[0003] Chinese Patent Application No. 202322034922.1 discloses a sanitary absorbent product, which, from top to bottom, comprises a surface layer, a covering layer, an absorbent core, and a leak-proof layer. The absorbent core includes an absorbent layer; the absorbent layer includes at least one layer of absorbent paper, and the absorbent layer has a perforated structure that protrudes from the lower surface of the absorbent layer. The perforated structure in this sanitary absorbent product forms a three-dimensional suspended honeycomb structure, which promotes the rate of absorption and increases breathability. However, this sanitary absorbent product does not address the issue of simultaneously and rapidly conducting urine both horizontally and vertically, resulting in a relatively slow absorption rate.

[0004] Chinese Patent Application No. 202322190247.1 discloses an absorbent core for diapers, comprising: a dust-free paper layer arranged sequentially from top to bottom; an absorbent core layer, which includes an upper absorbent resin layer, an absorbent core middle layer, and a lower absorbent resin layer arranged sequentially from top to bottom; and a non-woven fabric layer; wherein the upper absorbent resin layer is divided into at least three parts from left to right: a front part, a middle part, and a rear part, with the resin absorption time of the front part being 'a', the resin absorption time of the middle part being 'b', and the absorption time of the rear part being 'c', satisfying the quantitative relationship b > a and b > c. This absorbent core for diapers can effectively avoid gel blockage caused by absorbing liquid, ensuring lateral diffusion and vertical seepage of urine, and can also effectively lock in water to prevent backflow and leakage. However, this diaper has the problem of not having a receiving cavity and being unable to completely absorb urine, leading to leakage. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides a solution to the problem that existing diapers cannot quickly conduct urine in both horizontal and vertical directions at the same time, and that when the amount of urine is too large, they do not have a accommodating cavity and cannot be completely absorbed, resulting in leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fast-draining diaper with conical permeable holes includes a diaper body, the diaper body including an elastic waistband and an absorbent core connected to the elastic waistband, the length direction of the absorbent core is defined as longitudinal, the width direction of the absorbent core is defined as transverse, the two longitudinal ends of the absorbent core are connected to the elastic waistband, the absorbent core includes a skin-friendly surface layer, a diversion layer, an absorbent layer and a leak-proof bottom layer stacked from top to bottom, characterized in that: the surface of the skin-friendly surface layer is uniformly provided with a plurality of grooves, the grooves including transverse grooves and longitudinal grooves, the surface of the skin-friendly surface layer is also provided with conical permeable holes penetrating the absorbent layer, the size of the conical permeable holes gradually decreases from top to bottom, the conical permeable holes are uniformly distributed on the skin-friendly surface layer, the surface of the diversion layer is provided with a plurality of micropores, the absorbent layer includes at least one first superabsorbent resin layer, at least one fluff fiber layer and at least one second superabsorbent resin layer stacked from top to bottom, the leak-proof bottom layer includes an upper support layer and a lower leak-proof membrane, the support layer has a receiving cavity inside.

[0008] Furthermore, the depth of each of the conical permeation holes is 1-10 mm.

[0009] Furthermore, the distance between each of the conical permeation holes is 1-3 mm.

[0010] Furthermore, the water absorption rate of the first superabsorbent resin layer is greater than that of the second superabsorbent resin layer.

[0011] Furthermore, the micropores on the surface of the flow guide layer protrude toward the absorption layer.

[0012] Furthermore, the accommodating cavity is formed of a high-strength fiber mesh.

[0013] Furthermore, the depth of each of the pressure grooves is 0.7mm-1mm.

[0014] Furthermore, each of the aforementioned pressure grooves is in the shape of a straight strip.

[0015] Furthermore, each of the aforementioned pressure grooves is S-shaped.

[0016] Furthermore, each of the aforementioned pressure grooves is Z-shaped.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0018] 1. The skin-friendly surface layer has horizontal and vertical grooves, which can quickly absorb urine in both horizontal and vertical directions, and quickly and evenly transfer the liquid from the surface layer to a wider area, increasing the absorption area of ​​the absorption layer and improving the overall absorption efficiency.

[0019] 2. The surface of the skin-friendly layer is provided with conical permeable pores that penetrate the absorbent layer. The size of the conical permeable pores gradually decreases from top to bottom. During the permeation process, the urine will be guided to a certain extent, so that the urine can penetrate the skin-friendly layer more quickly and enter the guiding layer and the absorbent layer, while reducing liquid backflow.

[0020] 3. The surface of the diversion layer has several micropores, which can promote the rapid conduction of urine into the absorbent layer on the one hand, and improve the breathability of the diaper on the other hand.

[0021] 4. The water absorption rate of the first superabsorbent resin layer is set to be greater than that of the second superabsorbent resin layer, forming a water absorption gradient from large to small, which can ensure rapid liquid absorption;

[0022] 5. The support layer is located between the absorbent layer and the leak-proof bottom layer. It mainly serves as a support to prevent the absorbent layer from deforming or shifting. The support layer has a receiving cavity inside. When the layers above the leak-proof bottom layer fail to absorb all the urine, the excess urine will flow into the receiving cavity, thereby preventing urine from leaking to the outside of the diaper.
